I purchased a bluetooth transmitter with the thought of sending audio signal from my receiver to a small 6w powered bluetooth speaker at the rear of the room for some clarity and dialogue while using my 5.1 receiver while watching movies. Scrapped that idea when I noticed the audio on the bluetooth setup lags a bit behind the 5.1 system so I tried all the audio outs I have available and they all lagged. My last resort was wiring the bluetooth speaker to the center channel on my AVR which is already connected to my 6 ohm 60w center speaker, so I tried it just for the hell of it. I now have the sound I desired, but my 100w center channel on my AVR has the center channel speaker and the 6w bluetooth speaker wired to it. Watched a movie for about a half hour with it set up like this and it sounds great, nothing fried, and the fan on my receiver didn't turn on. Not sure what an 8 ohm output on my amp running a 6 ohm center speaker and a small powered 6w bluetooth speaker totals to in ohms, but it's probably not good for the amp.
